I don't have one like this but....
I do have a bit of advice in general if you do decide to go with this Sigma...
I have a Sigma that is more basic, with the cadence meter. I am very satisfied with this except for one thing...
I was riding awhile back in major wind and was trying to get the pepper spray lose from my handlebars because of a pooch up ahead. In the process of doing this and trying to figure out which way would be downwind if I had to spray the dog, I knocked my Sigma loose. The computer turns out of the "cage" that holds it on the handlbars so that you can take it in the house, put it on another bike, etc. Anyhow, with the wind, I didn't hear it rattle loose and come off. I was about two miles down the road when I noticed that it wasn't on the bike :( I turned around and spotted it in the middle of the road. Just as I saw it, a huge Suburban rolled over the top of it and smashed it to tiny bits. It was like one of those slow motion movies where I am thinking "NNNNOOOOOO" but can't do a thing about it.
I purchased a second one and used two of my daughters no slip/pull pony tail holders to keep it in place in case I loosen it by accident again.
My advice - if you do get a sigma, put some rubber bands around it to hold it on the bike so it doesn't get knocked lose.
There, I feel better now :D Good luck in your search!
